UNITED STATES WILLIAM S. HUNKINS, OF HOLLYWOOD, CALIFORNIA.

PIN TUBE.

Application filed October 7, 1924.

To all 1071.012], it may concern:

Be it known that I, WILLIAM S. HUNKINs, a citizen of the United States of America, residing at Hollywood, California, have 111- vented a new and useful Pin Tube, of which the following is a specification.

My invention relates to certain new and useful improvements in so-called pin tubes, which function to support the pin portion of a safety pin throughout a substantial portion of its length, so that, when under strain, it will not bend and thereby dislodge the point from the shield.

The main object of the present mventlon is to provide a tube which may be easily secured in place on a fabric support, and which, when secured in place, will not move out of position endwise or otherwise.

In the drawings- I Fig. 1 is a side elevation, partly in section, of a preferred form of tube, the same being on a very much enlarged scale;

Fig. 2 is a similar view, showing the tube held in place on a piece of webbing;

Fig. 3 is a view similar to Fig. 2, illustrating a modification;

Fig. l is a similar view, illustrating another modification.

In the form shown in Figs. 1 and 2. 1 rep resents the main body of the tube, having two expanded or bulged out annular enlargements 22 adjacent to the ends thereof and forming abutment shoulders for holding loops, 3 represents a short strip of webbin of a width approximately the length of the tube. l-at represent loops or thread or the like by which the tube is secured to said @webbing. It will be observed that these loops terminate adjacent to the abutment shoulders 2 2, and thus cudwise displacement: of the tube within the webbing is prevented. Ordinarily, if the tube is attached to a piece of webbing, such as indicated in Fig. 2, thewebbing would be folded on itself to form a short tab, the tube being located within the fold or bight thereof. These articles, including the web tab, may be vended as complete articles of manufacture, ready to be stitched onto a garment at any desired place; or, in some instances. the bare tubes may be vended so that they may be sewed directly onto the webbing or onto a. garment by the purchaser.

In Fig. 3 I have shown a modification, in

Serial No. 742,269. l

which a single abutment bulge occurs at about the middle of the tube, as indicated at 5. The presence of this abutment between the stitches or loops 6-6, which in this instance are located on opposite sides of the enlargement, serves to prevent the endwise displacement of the tube after it is secured in place. In this case the opposite sides of the bulge form, in effect, two shoulders.

In Fig. 4- I have shown another modification, in which the abutment shoulders appear directly at the ends of the tube, as indicated at 7-7. These abutments are formed by flaring outwardly the ends of the tube. Here again the tube may be stitched to the webbing 3 by thread loops 8 in the same manner as in Fig. 2, and the shoulders 77 will prevent the endwlse displacement of the tube relatively to the webbing 3. In this construction the shoulders 7 7, being bell shaped facilitate the easy entrance of the pin point into the tube and thereby perform a double function.

What I claim is:

1. As an article of manufacture, a pin tube of the character described, comprising a tubular body having an integral expanded portion constituting an abutment for engaging the sides of connector loops extended around said body.

2. As an article of manufacture, a pin tube of the character described, comprising a tubular body having an integral expanded portion constituting an abutment for engaging the sides of connector loops extended around said body, one of said abutments be ing provided adjacent each of said tube.

3. In a pin tube of the character described, a tubular body having an integral expanded portion directly at each end thereof formed by flaring outwardly the ends of said tube to provide two loop-engaging abutments and two enlarged pin entrances.

4. As an article of manufacture, a tab comprising a piece of webbing, a tube arranged transversely thercof, connector loops for holding said tube to said webbing, a portion of the tube being expanded outwardly to form an abutment for said conncctoi. loops, said connector loops being located closely adjacent to said abutment to check endwise movement of said tube relatively to said webbing.
